Answer:
(-2, 3)
Step-by-step explanation:
A is translated from (5, 1) to A' at (6, -2).
That is, it moves <em>one unit to the right and three units down</em>.
B is also translated to B' one unit to the right and three units down to (-1, 0).
B must be <em>one unit to the left and three units above B'</em>.
Thus, the coordinates of B are (-2, 3).
The diagram below shows the translation of side AB of ∆ABC to its new location at A'B'.

Answer:
40° and 9°
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
If the polygon is regular then the measure of each exterior angle is
← where n is the number of sides
(a) for a regular 9 sided polygon
exterior angle = = 40°
(b) for a regular 40 sided polygon
exterior angle = = 9°
